To all whom t may concern:

Be it known that I, FREDERICK JOHN GAI:- Niniz, subject of the King of Great Britain and ireland, residing at 16 Halkett street, St. Helier, Jersey, British isles, have invented a new and useful improvement in Sliding `Windows, of which the following is a specification.

rlhis invention relates to improvements in sliding windows and the like and more particularly to the means for retaining the window sashes in the desired open orclosed position.

The usual method of supporting sliding window sashes consists in the employment of sash cords and counterbalance weights. This method has many disadvantages inasmuch as when one or both of the sash lines become broken the window sash has to be removed and part of the window frame dismantled to enable a new cord to be fitted. Moreover the sashes are a very loose fit in the frame so that a tendency to vibrate or rattle very often results, especially when the window is partially open.

The object of the present invention consists in a simplified construction oi'i means for retaining or supporting the window sashes in their desired position, without the use of sash cords and weights, said means also securing the sashes against vibration during windy or rough weather.

According to the invention, l provide each sash on each side of the window frame with a loosely mounted rotatable roller or the like which is adapted to be pressed into frictional contact with the vertical sides of the window sash by a spring or weight, an annular ring or sleeve being preferably arranged in such a position as to extend between the roller or the like and the sash. rlhe roller is preferably mounted in a sliding fitting comprising a forked member suitably guided in a supporting frame or casing. The frame may also be provided with a removable back plate against which the rear end of the spring or springs (where springs are used), rest, said plate being easily removed so as to enable a broken spring to be replaced if desired.

In order that the invention may be readily understood reference is made to the accompany drawings in which Figure l is a front elevation of an ordinary sash window having the invention applied thereto.

F ig. 2 is a vertical section` on the line AHA of Fig. l with the sashes removed.

Fig. is a norizontal section on the line B-B Fig. 2 of one of the fittings.

Figs. 4. and 5 are sectional view and elevation respectively of one of the fittings.

Figs. (3 and 7 are similar views of a modified construction.

rihe construction shown in Figs. l to 5 comprises a frame a, in which is mounted two verticali;7 slidably sashes Y), o said sashes being guided in the usual manner between guides e, e. The vertical side members al of tho window frame are each provided with a recess or aperture to receive a supporting frame or casing f, one frame being provided on each side of each sash. rfliese frames comprise side members f/ between which is mounted a rotatable roller or the like L carried between the ends of a forked or U- shaped member z'. This forked member is formed or provided with a rearwardly eX- tending pin or the like Ze, the outer end of which passes through a hole in the rear por tion g1 of the frame. rlhe pin 7c carries a spring m normally tending to press the roller /i toward the side of the window sash.

Between the roller l1, and the ,.a. h is mounted an annular ring or sleeve yn. lThis sleeve is preferably of such size that part of its periphery passes freely between the sides g, while its diameter is sufficient to permit the remaining portion of its surface to eX- tend clear ofthe supporting frame as shown in Figs. 4L and 5. The end of the pin or the like 7" is preferably screwed to receive a nut or the like o to limit the inward movement of the roller, and permit the tension of the sprinO' to be adjusted.

In order that the roller It is suitably guided, its spindle 71?- is preferably extended to opposite ends to engage with slots g2 formed in the sides g of the supporting frame. f

ln the construction shown in Figs. 6 anc 7 the spring m presses at its outer end against a removable plate p, the upper and lower edges of which are curved or bent to embrace pins g, extending through the sides g. These pins may be secured by locking pins passed transversely therethrough at their ends outside the members g or if necessary they may be formed by screwed bolts or in any other suitable manner. struction permits `thesprings m to be easily replaced in case of breakage.

lThe front end of the supporting frame is provided with a flanged plate 1 or the like adapted to be screwed to the Window frame', said plate being provided With a suitable aperture or slot through which the sleeven projects.

The details of construction may if necessary be modified Without departing from the principle of the invention.

It will be seen that when in operation, each of the Window sashes is supported by the rollers pressing inwardly toward the opposite vertical sides thereof. In this manner not -only are the sashes effectively supported, but vibration of the sashes in the Window frame is prevented While the samevcan be easily and readily raised or lowered as de-V siret What I claim as inv invention and *desire to obtain by Lettersatent is l. In sliding Windows, sashes adapted to k'slidein'the Window frame, recesses in the Window frame, rollers located in these recesses, annular rings arranged laround the rollers, and' means for resiliently pressing the rollers against the rings, and the rings This conl against the sliding sashes. Y 3. In slidingy Windows, sashes adapted to slide in the Window frame, recesses in the window frame, supporting frames in these` recesses, pins engaging in slots` in the sides of the supporting frames, rollers mounted on these pins, annular rings arranged around the rollers, and means for resiliently Vpressing the rollers against the rings, and the rings against the sliding sashes.

4. In sliding Windows, sashes adapted to slide in the Window frame, recesses in the Window frame, supporting frames in these recesses, a removable rear plate to the supporting frame, pins upon Vwhich the rear plate is mounted, rollers mounted in forked members, annular rings arranged around the y rollers, and means for resiliently pressing the rollers against the rings and the rings against vthe sliding sashes. f
